  1. 1. Systems Modeling Approaches to Physical Resource Management : An Industrial Ecology Perspective

    Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. LÄS MER

  2. 2. On Efficient Modelling of Wheel-Rail Contact in Vehicle Dynamics Simulation

    Författare :Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Asier Alonso; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; rail vehicle dynamics; rolling contact; vehicle-track interaction; wheel-rail damage; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The wheel-rail contact is at the core of all research related to vehicletrackinteraction. This tiny interface governs the dynamic performanceof rail vehicles through the forces it transmits and, like any high stressconcentration zone, it is subjected to serious damage phenomena. LÄS MER

  3. 3. Modeling and Simulation of Electricity Consumption Profiles in the Northern European Building Stock

    Författare :Claes Sandels; Lars Nordström; Palensky Peter; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand Response; Flexible loads; Building stock energy-use; Bottom-up simulation models; Load profiles; Non-homogeneous Markov-chains; End-user behavior; Lumped capacitance models; HVAC system control; Smart Grid.; Efterfrågeflexibilitet; Flexibla laster; Energianvändning i byggnadsstocken; Botten-upp-simuleringsmodeller; Elförbrukningsprofiler; Icke-homogena Markovkedjor; Slutanvändarbeteenden; Värmedynamikmodellering; Styrning av HVAC-laster; Smarta elnät.;

    Sammanfattning : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. LÄS MER

  4. 4. Generative Design Exploration : Computation and Material Practice

    Författare :Mania Aghaei Meibodi; Oliver Tessmann; Jonas Runberger; Neil Leach; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Architecture; Arkitektur;

    Sammanfattning : Today, computation serves as an important intermediary agent for the integration of analyses and the constraints of materialisation into design processes. Research efforts in the field have emphasised digital continuity and conformity between different aspects of a building project. LÄS MER

  5. 5. Synthesis of AcGGM Polysaccharide Hydrogels
